专题九 情态动词
一对一“梳理”知识点
高效复习法
中考对于情态动词的考查主要是其基本用法和表推测的用法.对于考查基本用法的试题,考生应首先看有无涉及各情态动词的常用句型,如“May I...?”“Can/Could you...?”.如果没有,先分析各选项的含义,然后根据语境确定正确答案;如果有,则根据问句中的常用句型选择相应的答语或正确的情态动词.
对于考查情态动词表推测的试题,考生可从以下两方面着手:①表示否定的推测:根据语境,对空格处若判断是否定,此时用can't;如果语气不是很肯定,常用may not或might not表否定推测,意为“可能不,也许不”.②表示肯定的推测:如果语境有非常明显的表示肯定的提示词,则直接选must;如果是表示不能十分肯定或拿不准,此类题一般也会有相关的语境提示,如:I'm not sure, who knows,此时用may或might.
